Also known as drug release; delivery of the active ingredient from a dosage form into solution is called?

• A. Liberation
• B. Absorption
• C. Biotransformation
• D. A and B

Answer: (A)

Drug release is the step where the active ingredient is separated from its dosage form and enters solution in the surrounding fluid. This is called liberation. It must happen before absorption, which is the movement of the dissolved drug into the bloodstream. Biotransformation refers to metabolism, not release. So the process described—delivery into solution from the dosage form—fits liberation.
